Revert "Unify CPU features detection code"
This reverts commit 6f7e5e79cefe982ad84a88927565a88db2e592be.
Reason for revert: This broke the build, e.g.
https://ci.chromium.org/p/chromium/builders/ci/ios-device/144512
../../third_party/zlib/cpu_features.c:75:13: error: unused function '_cpu_check_features' [-Werror,-Wunused-function]
static void _cpu_check_features(void)

Original change's description:
> Unify CPU features detection code
>
> This will allow to remove some duplicated code (i.e. thread synchronization)
> while at same time removing unnecessary use of inline ASM for Intel features
> detection.
>
> A few other advantages:
> - remove some extra logic (e.g. no need to test the platform to include the
> correct CPU detection header).
> - simplifies the buildsystem (i.e. we always include cpu_features.c)
> - get rid of the simd_stub file.
